TIMEMORE Chestnut C3S Pro Manual Coffee Grinder, Stainless Steel S2C Conical Burr Coffee Grinder, Hand Coffee Grinder with Foldable Handle, Adjustable Grind Setting for Travel/Camping/Home, Black

A reliable hand coffee grinder gives travelers and home brewers full control over their fresh cup without the clutter of cords or bulky motorized bases. The TIMEMORE C3S Pro tackles the everyday challenge of grind consistency by combining a rigid full-metal housing with precision-cut burrs. Designed to serve both morning kitchen routines and mobile setups, it packages durable parts into an easy-to-pack shape that handles regular use without unnecessary bulk.

The build centers on an all-metal aluminum alloy body paired with TIMEMORE's patented S2C660 hexagonal conical burr set. Machined using 5-axis CNC equipment to achieve 55-58HRC hardness, these stainless steel milling blades cut through beans cleanly. The burr geometry produces uniform particle sizes with minimal overly coarse pieces and reduces the creation of excess fine dust. Beyond physical durability, the aluminum body aids heat dissipation as you crank, which prevents excess warmth from altering the natural flavors locked inside your beans.

Daily usability benefits significantly from smart mechanical details. The grinder body measures just 52 mm across, making it easy to hold securely during grinding even if you have smaller hands. Inside, a dedicated bearing system reduces friction, allowing the crank to spin smoothly and keep turning briefly even after you take your hand away. When your prep is done, the foldable crank handle tucks neatly against the unit, eliminating awkward protruding parts so you can slide it directly into a small bag, backpack, or tight kitchen drawer.

Dialing in your desired texture is managed by an adjustment nut that shifts through roughly 36 distinct levels. Turning the nut clockwise produces finer powder for concentrated brewing, while rotating it counter-clockwise shifts toward coarser grounds suited for immersion or drip methods. Because the mechanism uses clear mechanical steps, you can switch back and forth between different brew styles with dependable repeatability.

As a compact manual unit, it naturally comes with inherent trade-offs. Grinding beans by hand takes physical participation for every single cup, which might feel slow if you need to serve multiple guests back-to-back. Its slim, travel-focused frame also means bean capacity is built around single-serve prep rather than big carafes, making it best suited for individual drinkers or outdoor adventures.

Verdict: The TIMEMORE C3S Pro is a strong choice for solo coffee drinkers, campers, and frequent travelers who value sturdy metal construction, smooth operation, and fine grind control. Those needing high-volume brewing for large groups or effortless push-button operation will be better served by a full-sized electric machine.

• Body Material: All-metal aluminum alloy
• Burr Type: S2C660 patent hexagonal conical burr
• Burr Hardness: 55-58HRC (5-axis CNC machined)
• Body Diameter: 52 mm
• Coarseness Settings: Approx 36 levels
• Handle Design: Foldable crank handle
• Color: Black

A great fit if you:

• Brew coffee on camping trips or while traveling and need a foldable handle that saves storage room in your luggage.
• Want reliable particle consistency from hardened 55-58HRC conical burrs without dealing with electric cords or counter clutter.
• Have smaller hands and prefer a slim 52 mm grinder body that stays easy to grip during grinding.
• Appreciate an all-metal aluminum alloy construction that withstands frequent transport and regular daily handling.

Consider something else if you:

• Regularly brew multi-cup carafes for large groups and would prefer a high-capacity electric grinder to avoid multiple manual batches.
• Experience limited hand strength or wrist discomfort that makes turning a manual crank handle challenging.

Confirm on the listing:

• Check whether the package includes any carrying pouch or cleaning brush alongside the grinder.
• Review the bean hopper and grounds container capacity if you frequently brew larger cups at once.
• Confirm the exact packed height and weight if you have strict packing limits for your travel gear.
• Check the included documentation for specific guidance on zeroing out the coarseness adjustment nut.

How to compare your options: Focus on core build material, burr geometry, and portability features when weighing manual grinders. The TIMEMORE C3S Pro distinguishes itself with a full aluminum alloy housing rather than plastic components, CNC-machined S2C660 burrs for uniform cutting, and a folding handle that reduces packed volume. Match these features against your routine to decide whether its slim 52 mm body and 36 settings meet your brewing goals.

Keep these habits in mind to enjoy smooth, dependable performance from your manual grinder over time:

• Set your grind size before loading beans by turning the adjustment nut clockwise toward fine or counter-clockwise toward coarse to reach your intended level.
• Maintain a firm, upright grip on the 52 mm aluminum body while turning the crank to ensure steady, balanced rotation through the built-in bearing.
• Fold the handle down flat after each grinding session to prevent accidental bumps on your counter and to pack it safely for travel.
• Brush out residual grounds from the burr assembly regularly as recommended by the care guide to keep the stainless steel milling surfaces clear.

How do you adjust the grind coarseness on this unit?
You adjust coarseness by rotating the internal adjustment nut. Turning the nut clockwise results in a finer grind, while turning it counter-clockwise shifts the settings toward a coarser texture across approximately 36 levels.

What kind of burrs are inside the TIMEMORE C3S Pro?
It features patented S2C660 hexagonal conical burrs. These burrs are crafted through 5-axis CNC machining to reach a hardness of 55-58HRC, promoting uniform particles and reducing fine powder.

Does the handle detach for travel?
The crank handle folds rather than detaching completely. This folding design lets it collapse compactly against the body to save storage space at home or on trips.

Is the outer body made of plastic or metal?
The body is constructed from an all-metal aluminum alloy. This metal design protects internal parts and helps dissipate heat generated during grinding sessions.

How many beans can the hopper hold at one time?
The listing does not state the exact bean or grounds capacity in grams. If you plan to brew large multi-cup batches, check the product details on the seller page for specific capacity measurements.
